I sometimes hear the word “おしゃれい” or “my boom” when I listen to Japanese conversations.
おしゃれい:Stylish, fashionable, or fancy. For example,
This is a very stylish restaurant. My best friend is very fashionable. I like to buy fancy things.
“My boom”: Obsess or obsessed with something, very interested in something. For example,
I am obsessed with the new song by Mr. Children. (Obsess can have a strong meaning of really, really liking something. This can sometimes have a negative meaning.) For example,
My ex-girlfriend was obsessed with me, so I decided to break up with her.
Recently I am very interested in Korean dramas.
